(e) If, at any time when a prospectus relating to the Securities is required to be delivered under the Act (or in lieu thereof, the notice referred to in Rule 173(a) under the Act), any event occurs in the reasonable judgment of the Representative or the Company as a result of which the Registration Statement, the Pricing Disclosure Package (prior to the availability of the Prospectus) or the Prospectus as then amended or supplemented would include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary at any time to amend or supplement the Registration Statement, the Pricing Disclosure Package or the Prospectus or to file under the Exchange Act any document incorporated by reference in the Registration Statement, the Pricing Disclosure Package or the Prospectus in order to comply with the Act, the Exchange Act or the Trust Indenture Act, if applicable, the Company will promptly notify the Representative and will prepare and file with the Commission, subject to Section 4(a) herein, an amendment or supplement which will correct such statement or omission or an amendment which will effect such compliance.

(f) The Company will not, without the prior consent of the Representative, (A) make any offer relating to the Securities that would constitute a “free writing prospectus” as defined in

11

Rule 405 under the Act, except for any Issuer Free Writing Prospectus set forth in Schedule B hereto, or (B) file, refer to, approve, use or authorize the use of any “free writing prospectus” as defined in Rule 405 under the Act with respect to the Offering or the Securities other than as set forth in Schedule B hereto. The Company consents to the use by any Underwriter of any free writing prospectus that (a) is not an “issuer free writing prospectus” as defined in Rule 433, and (b) contains only (i) information describing the preliminary terms of the Securities or their offering and that is included in any Preliminary Prospectus, (ii) information that describes the final terms of the Securities or their offering and that is included in the term sheet of the Company contemplated in Section (4)(b) of this Agreement or (iii) information permitted by Rule 134 under the Act. Notwithstanding any of the foregoing to the contrary, except pursuant to Section 4(f) hereof, no Underwriter shall include any “issuer information” (as defined in Rule 433) in any “free writing prospectus” (as defined in Rule 405) used or referred to by such Underwriter without the prior consent of the Company where the use or reference to such free writing prospectus would require the filing of such “issuer information” with the Commission pursuant to Rule 433(d) due to the Underwriters’ inclusion of such “issuer information” in any “free writing prospectus”.

(g) If at any time any event shall have occurred as a result of which any Issuer Free Writing Prospectus as then amended or supplemented would, in the judgment of the Representative or the Company, conflict with the information in the Registration Statement, the Preliminary Prospectus or the Prospectus as then amended or supplemented, or would, in the judgment of the Representative or the Company, include, when taken together with the Pricing Disclosure Package, an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances existing at the time of delivery to the purchaser, not misleading, or if to comply with the Act or the Rules and Regulations it shall be necessary at any time to amend or supplement any Issuer Free Writing Prospectus, the Company will notify the Representative promptly and, if requested by the Representative, prepare and furnish without charge to each Underwriter an appropriate amendment or supplement (in form and substance reasonably satisfactory to the Representative) that will correct such statement, omission or conflict or effect such compliance.

(h) As soon as practicable after the date hereof, but in no event later than twelve months after the effective date of the Registration Statement (as defined in Rule 158(c) under the Act), the Company will make generally available to its security holders an earnings statement which will satisfy the provisions of Section 11(a) of the Act.

(i) The Company will furnish to the Representative copies of the Registration Statement, including all exhibits, any Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus, all amendments and supplements to such documents, and all documents incorporated by reference in the Registration Statement, any Preliminary Prospectus and the Prospectus, in each case as soon as available and in such quantities as are reasonably requested.

(j) The Company will arrange for the qualification of the Securities for sale under the laws of such jurisdictions as the Representative reasonably designates and will continue such qualifications in effect so long as required for the distribution, except that in no event shall the Company be obligated in connection therewith to qualify as a foreign corporation, to execute a general consent to service of process or to subject itself to taxation in any such jurisdiction if it is not otherwise so subject.

12

(k) During the period in which the Securities remain outstanding, the Company will furnish to the Representative and, upon request, to each of the other Underwriters, if any, as soon as practicable after the end of each fiscal year, a copy of its annual report to stockholders for such year; and the Company will furnish to the Representative (i) as soon as available, a copy of each report or definitive proxy statement of the Company filed with the Commission under the Exchange Act or mailed to stockholders, and (ii) from time to time, such other information concerning the Company as the Representative may reasonably request.

(l) The Company will pay the costs incident to the authorization, issuance, sale and delivery of the Securities to be sold by the Company to the Underwriters and any taxes payable in that connection; the costs incident to the preparation, printing and filing under the Act of the Registration Statement and any amendments and exhibits thereto; the costs incident to the preparation, printing and filing of any document and any amendments and exhibits thereto required to be filed by the Company under the Exchange Act; the cost of distributing the Registration Statement to the Underwriters as originally filed and each amendment thereto, each post-effective amendment thereof (including exhibits), any Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus and any amendments or supplements to or any documents incorporated by reference in any of the foregoing documents as provided in this Agreement; the costs of filing with the Financial Industry Regulatory Authority, Inc., if necessary; the fees and expenses of qualifying the Securities under the securities laws of the several jurisdictions as provided in this subsection and of preparing a Blue Sky memorandum and a memorandum concerning the legality of the Securities as an investment (including fees of counsel to the Underwriters in connection therewith); the costs of printing and issuance of certificates; the costs of preparation, printing and filing of any Indenture and any Trustees’ fees and expenses; and all other costs and expenses incident to the performance of the obligations of the Company under this Agreement; provided that, except as provided in this subsection and Section 8, the Underwriters shall pay their own costs and expenses, including the fees and expenses of their counsel, any transfer taxes on the Securities which they may sell, the expenses of advertising any offering of the Securities made by the Underwriters and the cost of printing any Agreement among Underwriters; provided, further, that after nine months from the date hereof, the Underwriters shall pay the costs of printing any additional Registration Statements or Prospectuses, or any amendments or supplements thereto, required for their own use.

(m) Without the prior consent of the Representative, the Company will not, for a period beginning at the Applicable Time and ending 40 days thereafter, offer, sell, contract to sell or otherwise dispose of any debt securities of the Company with maturities longer than one year, other than (i) the Securities to the Underwriters; (ii) borrowings in the ordinary course of business; and (iii) other borrowings in an aggregate principal amount not to exceed $100 million.

(n) The Company will not take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in, under the Exchange Act or otherwise, stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities.

13

(o) Substantially concurrently with the closing of the offering of the Securities, the Company will issue a notice of redemption for its outstanding 12 ³/₄% Senior Secured Notes Due 2014, pursuant to the indenture governing such notes.

(p) The Company will apply the net proceeds from the sale of the Securities as described in the Registration Statement, the Pricing Prospectus and the Prospectus.

5. Conditions of the Obligations of the Underwriters.

(c) Subsequent to the Applicable Time, there shall not have occurred (i) any change, or a development that would reasonably be expected to result in a change, in or affecting the business, financial condition, results of operations or stockholder’s equity of the Company and its subsidiaries, taken as a whole, which, in the judgment of the Representative, makes it impractical or inadvisable to market the Securities or proceed with completion of the sale of and payment for the Securities; (ii) any downgrading, or placement on any watch list for possible downgrading, in the rating of the Company’s debt securities by any of Standard & Poor’s Corporation or Moody’s Investors Services, Inc.; (iii) any suspension of trading in securities generally on the New York Stock Exchange, or any setting of minimum prices for trading on such exchange, or any suspension of trading of any securities of the Company on any exchange or in the over-the-counter market; (iv) any banking moratorium declared by Federal or New York authorities; or (v)(A) any outbreak or escalation of major hostilities or acts of terrorism in which the United States is involved, any declaration of war by the United States Congress or (B) any other substantial national or international calamity or emergency, or any substantial change in political, financial or economic conditions or currency exchange rates or exchange controls if the effect of any such event in clause (A) or (B) of this sentence, in the judgment of the Representative, makes impractical or inadvisable to market the Securities or proceed with completion of the sale of and payment for the Securities.

14

(d) The Representative shall have received an opinion and negative assurance letter, dated the Closing Date, from Simpson Thacher & Bartlett LLP, counsel for the Company; such opinion and negative assurance letter to be in form and substance reasonably satisfactory to the Underwriters, substantially to the effect set forth in Schedule D hereto.

6. Indemnification and Contribution. (a) The Company will indemnify and hold harmless each Underwriter and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act and each selling agent of any Underwriter against any losses, claims, damages, or liabilities whatsoever, joint or several, to which such Underwriter may become subject, under the Act, the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in (A) the Registration Statement or in any amendment thereof, or in any Preliminary Prospectus, the Pricing Disclosure Package or the Prospectus, or in any supplement thereto or amendment thereof, or in any Issuer Free Writing Prospectus, or in any “issuer information” (as defined in Rule 433(h)(2) under the Act) filed or required to be filed pursuant to Rule 433(d) under the Act, or (B) any other “written communication” (as defined in Rule 405 under the Act) provided to investors by, or with the approval of, the Company in connection with the Offering and any

15

“road show” (as defined in Rule 433 under the Act ) for the Offering (collectively, “Marketing Materials”), or (ii) the omission or alleged omission to state (A) in the Registration Statement or any amendment thereof, a material fact required to be stated therein or necessary to make the statements therein not misleading, or (B) in any Preliminary Prospectus, the Pricing Disclosure Package or the Prospectus, or in any supplement thereto or amendment thereof, or in any Issuer Free Writing Prospectus, or in any “issuer information” (as defined in Rule 433(h)(2) under the Act ) filed or required to be filed pursuant to Rule 433(d) under the Act, or in any Marketing Materials, a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; and the Company will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter through the Representative, if any, specifically for use therein.

(b) Each Underwriter, severally and not jointly, will indemnify and hold harmless the Company, its directors, its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities to which the Company may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement any amendment thereof, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or (ii) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Pricing Disclosure Package or the Prospectus, or in any amendment thereof or supplement thereto, any Issuer Free Writing Prospectus, or any “issuer information” (as defined in Rule 433(h)(2) under the Act) filed or required to be filed pursuant to Rule 433(d) under the Act or any Marketing Materials, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Underwriter through the Representative, specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred. The Company acknowledges that (i) the statements set forth in the last paragraph of the cover page regarding delivery of the Securities and, under the heading “Underwriting,” (ii) the list of Underwriters and their respective participation in the sale of the Securities, (iii) the sentences related to concessions and reallowances and (iv) the paragraph related to stabilization, syndicate covering transactions and penalty bids in any Preliminary Prospectus and the Prospectus constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in any Preliminary Prospectus, the Pricing Disclosure Package, the Prospectus, any Issuer Free Writing Prospectus or Marketing Materials.

16

(c) Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under subsection (a) or (b) above notify the indemnifying party of the commencement thereof; but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party otherwise than under subsection (a) or (b) above. In case any sub action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided that the Representative shall have the right to employ one counsel (in addition to one local counsel) to represent the Representative and those other Underwriters who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Underwriters against the Company under this Section if, in the reasonable judgment of outside counsel to the Underwriters, it is advisable for the Representative and those other Underwriters to be represented by separate counsel because separate defenses are available to such Underwriters, and in that event the reasonable fees and expenses of such separate counsel shall be paid by the Company. No indemnifying party shall, without the prior written consent of the indemnified parties, effect any settlement or compromise of, or consent to the entry of judgment with respect to, any pending or threatened claim, investigation, action or proceeding in respect of which the indemnified party is or reasonably could have been a party and indemnity or contribution may or could have been sought hereunder by the indemnified party, unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such claim, investigation, action or proceeding and (ii) does not include a statement as to or an admission of fault, culpability or any failure to act, by or on behalf of the indemnified party.

(d) If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in the clause (i) above but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the

17

Underwriters. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section were to be determined by pro rata allocation (even if the Underwriters were treated as one entity for such purposes) or by any other method of allocation which does not take into account the equitable considerations referred to herein. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the aggregate underwriting discounts and commissions received by it exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint.

(e) The obligations of the Company under this Section shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act; and the obligations of the Underwriters under this Section shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each director of the Company, to each officer of the Company who has signed the Registration Statement and to each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act.

7. Default of Underwriters. If any Underwriter or Underwriters default in their obligations to purchase securities hereunder and the aggregate amount of the Securities that such defaulting Underwriter of Underwriters agreed but failed to purchase does not exceed 10% of the total amount of the Securities, the Representative may make arrangements satisfactory to the Company for the purchase of such Securities by other persons, including any of the Underwriters, but if no such arrangements are made by the Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments under this Agreement, to purchase the Securities that such defaulting Underwriters agreed but fail to purchase. If any Underwriter or Underwriters so default and the aggregate amount of the Securities with respect to which such default or defaults occur exceeds 10% of the total amount of the Securities and arrangements satisfactory to the Representative and the Company for the purchase of such Securities by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter or the Company, except as provided in Section 8. As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section. Nothing herein will relieve a defaulting Underwriter from liability for its default. The respective commitments of the

18

several Underwriters for the purposes of this Section shall be determined without regard to reduction in the respective Underwriters’ obligations to purchase the amounts of the Securities set forth opposite their names in Schedule A hereto.

8. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Company or its officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any termination of this Agreement or any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Company or any of their respective representatives, officers or directors or any controlling person and will survive delivery of and payment for the Securities. If the obligations of the Underwriters with respect to any offering of Securities are terminated pursuant to Section 7 or if for any reason the purchase of the Securities by the Underwriters hereunder is not consummated, the Company shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 4(l) and the respective obligations of the Company and the Underwriters pursuant to Section 6 shall remain in effect. If for any reason the purchase of the Securities by the Underwriters is not consummated other than because of the termination of this Agreement pursuant to Section 7 or a failure to satisfy the conditions set forth in Section 5(c), the Company shall reimburse the Underwriters, severally, for all out f-pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Securities. The provisions of Sections 11 and 13 shall also survive any termination or modification of this Agreement.

9. No Fiduciary Duty. The Company hereby acknowledges and agrees that, with respect to the offering of Securities pursuant to this Agreement, (i) the terms of this Agreement, and the offering of the Securities (including the price of the Securities) were negotiated at arm’s length between sophisticated parties represented by counsel; (ii) no fiduciary, advisory or agency relationship between the Company on the one hand, and the Underwriters on the other hand has been created as a result of any of the transactions contemplated by this Agreement or the process leading to such transactions, irrespective of whether any Underwriter has advised or is advising the Company on other matters, (iii) the Underwriter’s obligations to the Company in respect of the Offering are set forth in this Agreement in their entirety and (iv) the Company has obtained such legal, tax, accounting and other advice as they deem appropriate with respect to this Agreement and the transactions contemplated hereby and any other activities undertaken in connection therewith, and the Company is not relying on the Underwriters with respect to any such matters. The Company hereby agrees that it will not claim that the Underwriters, or any of them, has rendered advisory services of any nature or respect to the Company, or owes a fiduciary or similar duty to it, in connection with such transaction or the process leading thereto.

10. Notices. All communications hereunder will be in writing and, if sent to the Company, will be mailed, delivered, telexed or telecopied and confirmed to it at 801 Lakeview Drive, Suite 100, Blue Bell, Pennsylvania 19422, Attention: Treasurer, with a copy to the Chief Financial Officer.

11. Successors. This Agreement will inure to the benefit of and be binding upon the Company and such Underwriters as are identified in this Agreement and their respective successors and the officers and directors and controlling persons referred to in Section 6, and no other person will have any right or obligation hereunder. No purchaser of any of the Securities from any Underwriter shall be deemed a successor or assign merely because of such purchase.

12. Certain Definitions. For purposes of this Agreement, (a) “business day” means any day on which the New York Stock Exchange is open for trading and (b) “subsidiary” and “significant subsidiary” have the meanings set forth in Rule 405 of the Rules and Regulations.

13. Applicable Law; Waiver of Jury Trial. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York, including, without limitation, Section 5-1401 of the New York General Obligations Law. The Company and the Underwriters agree that any suit or proceeding arising in respect of this Agreement or our engagement will be tried exclusively in the U.S. District Court for the Southern District of New York or, if that court does not have subject matter jurisdiction, in any state court located in The City and County of New York and the Company and the Underwriters agree to submit to the jurisdiction of, and to venue in, such courts. The Company and each of the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

14. Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.
